I saw this at the DC Environmental Film Festival. I didn't know to expect, given the audience, but the crowd really enjoyed the movie. So unlike many of the people reviewing here, I've actually seen the film. There was also a panel of experts discussing the film after the showing, and they did the best they could to answer audience member questions.
This film addresses pretty much every argument you might have against GMOS, and then show how the claims against them are untrue. Issues of health, safety, environment, big business, corporate shills, weed resistance, pesticides, yield, etc. and correct the misinformation that 's out there on the web by talking to actual scientists who actually work with GMOs. A much better source than some random person who opposes them, don't you think?
This is an excellent film to watch if you're not sure where you stand on the issue of GMOs, or have heard a bit about it, but don't know enough to really go either way. If you are completely closed- minded about the issue, then don't bother, because no amount of science, logic, and reason is going to change your mind, to paraphrase Tamar Haspel in the movie.
